關於點火補正,小弟搜尋到的觀念是
一、點火與引擎轉速的關係
1000rpm 與 2000rpm時,活塞抵達上死點的速度不一樣
所以基本上是隨著轉速增加來進角(正比)
二、點火與增壓值的關係
增壓值越大,缸內壓力高,活塞抵達上死點的速度越慢
所以隨著增壓值的提升,要適當地退角(反比)
原本店家寫好的點火補正

基於這樣的觀念,我將負壓範圍的點火角都做了一點進角

增壓的部份因為是之前店家寫好的我不敢亂動
爆震不太會判斷怕增壓時炸掉
最明顯的差異是
一、怠速抖動變小
二、怠速時含氧感知器的動作變快了(應該說變正常,之前有點鈍)
三、起步變得有力,加速也變得順暢許多
請問板上高手們,這樣的想法與做法會不會有什麼問題?
